Extruded polystyrene boards are widely used in dry wall insulation, steel structure roof insulation, and are also used for moisture-proof insulation in low-temperature storage floors, airport runways, highways and other fields. They are inexpensive and high-quality insulation and moisture-proof materials in the construction industry. The product features are as follows：
- Excellent and long-lasting thermal insulation
Extruded polystyrene board is mainly made of polystyrene, which is an excellent low thermal conductivity material. With the help of extrusion, the compact honeycomb structure can effectively prevent heat conduction. The thermal conductivity of the energy-gathering board is 0.028W/m·k, which has the characteristics of high thermal resistance and low linear expansion rate.
- Excellent water and moisture resistance
The extruded polystyrene board has a tight closed-cell structure, the polystyrene molecular structure does not absorb water, and there are no gaps on the front and back of the board, so the water absorption rate is extremely low, and the moisture-proof and anti-penetration properties are excellent.
- Corrosion resistance and durability
General rigid foam insulation materials tend to age after a few years of use, which in turn leads to water absorption and performance degradation. However, extruded polystyrene boards have excellent corrosion resistance, anti-aging, and thermal insulation properties, and can still maintain their excellent performance under high water vapor pressure, with a service life of up to several decades.
